Each one is designed to assess your abilities to identify a simple problem that might actually be harder than it first appears.

Not only do boffins claim that getting the right answer is a sign of genius, but also the time frame in which you come up with your solution.

Take the world's shortest IQ test

A bat and a ball cost £1.10 in total. The bat costs £1.00 more than the ball. How much does the ball cost?

If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?

In a lake, there is a patch of lily pads. Every day, the patch doubles in size.
If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

Now you’ve had a crack at the questions, the chances are you answered 10p for question 1, 100 minutes for question 2 and 24 days for question 3.

If you did, you are wrong.

Scroll down to see the correct answers to the test, and the workings behind each one.

1. The ball would actually cost 0.05 pence.

If the bat costs £1 more than the bat, you need to think outside the box.

While it might be easy to assume that the ball is 10p, that would make the bat £1.10 as it costs £1 MORE than the ball.

In order to keep the total at £1.10, the ball HAS to be 5p – and the bat worth £1.05.

2. It would take 5 minutes to make 100 widgets

Five machines can make five widgets in five minutes.

This means that one machine will make a widget in five minutes, too.

Therefore, 100 machines all making widgets can make 100 widgets in 5 minutes.
